The TE Connectivity 5502781-3 is a simplex fiber optic adapter that converts from an SC receptacle to an FC receptacle, letting you join SC-terminated patch cables to FC-terminated equipment or panels. It accepts both Singlemode and Multimode fibers, so it works across singlemode and multimode link budgets without swapping hardware. The metal ferrule gives the alignment sleeve better dimensional stability than a plastic one — important when you're mating connectors repeatedly in a patch panel or test setup.
Mounting and Build Details
The adapter mounts in a panel cutout using both a flange and snap-in clips — the flange takes the axial load from cable tugging, while the snap-in holds it in place during installation. A dust cap is included to keep the alignment sleeve clean when the port is not in use.
